To all whom it may Be it known that I, HENRY citizen of the United States, residing H. Dyna, a at Somervi'lle, inthe county of Sufiolk and- State of Massachusetts, have invented certain new and useful Improvements in Pocket-Filters, of which the following is a specification.

This invention is designed primarily to construct afilter which may be carried in 1 the pocket of the user,.and thus be an article 1 which will be desired by travelers, huntsmen, etc. I This device is constructed so that it may 16 be easily taken apart or assembled, and 1s provided with-a telescoping sectionwhich is inserted in the mouth of the user for drawing the liquid ,through the filter and thence into the mouth.

With the above and other objects in view, this invention consists in the construction,

combination, and arrangement of parts,;a ll

The 0 posite' terminal of the section, 7 is provided with. internal screw threads whic engage the external screw threads of the mouth piece orconical member 9, the latter being provided with. a central bole or opening in which'the' section 8 is adapted to reciprocate.

This slot 12 is so located as to be concealed when-the telescopic member is secured to the filter bod and thereby accidental displaceos's of the p ate 13. is prevented.
